It is undeniable that the pandemic and the use of masks has brought very positive things. For example, in airplanes: people leave orderly without being run over by any desperate from the back rows and mount a monumental traffic jam in the corridor. In elevators, for example, it is well seen not to wait politely for another neighbor to go up with him, you can close the elevator in all his face that he will even think well of you. You can also talk alone on the street without the need, as before, to pretend a conversation on your mobile. Or in the gym, you can wriggle in pain with your abs without anyone seeing anything more expressive of you than your eyes as illuminated by God. .
